摘要

Based on the measured impedance frequency response, this paper proposes a behavioral model of any common-mode choke (CMC) with magnetic core that exhibits frequency-dependent permeability. The model consists of several cascaded RLC parallel circuit blocks that resembles the actual measured impedance response in the frequency range of interest. The iterative algorithm to construct these RLC circuit...
